. which the briquets are i'ormed by compression in the molds between the coacting cylinders and are discharged by suitable means.

The particular improvements which form the subject matter of this application relate to the construction of the mold cylinders; to means for introducing steam to the interior of the cylinders; to means for catching and discharging the condensation from the steam; and to means fordischarging the molded briquets from their respective mold sockets where such discharge is not effectedthrough gravity.

An important object of this invention is to produce a. machine of the character named which will be of simple construction and therefore can be built economically; in which material adapted to the manufacture of briquets or similar products can be economically manufactured andin which'the manufacturing processes are facilitated through the application of 'heat.

Having the aforcgoing and other objects of general utility in view I have produced a machine which is shown in preferred construction in the accompanying drawings which form a part of this application and in which:

Figure 1 is a side elevation of the machine: with a portion of the hopper broken away; Fig. 2 is a vertical section, on an enlarged scale throughone of the cylinders which forms an important element of my invention; Fig. 3 is an end elevation of the machine; Fig.

,4 is a longitudinal section through the machine with the hopper removed; Fig. 5 is a top plan view of the machine complete, Fig. 6 is a longitudinal section in a horizontal plane through the machine; Fig. 7 is a detail on an enlarged scale of one of the adjustable journal blocks which form an element of my invention, and Fig.8 is a plan view of one of the briquets as produced by my machine.

Referring to the details of the drawings, 1 represents the main supporting frame of my machine which is a parallelogram in form and is provided with suitable vertical standards, and a top rail all of which may be formed and connected in any manner desirablev Rotatably mounted insuitable bearings to be described, are two shafts 2, 2, on which are respectively mounted and'secu'red, in any suitable manner, cylinders 3, 3, and also, on opposite sides of each cylinder, gears 4, 4.

- Suitably journaled in upper extensions 1 of the frame 1 is a shaft 6 on which pinions 5, 5, are fixed and on the outer end of which is secured a drive-wheel 7 to which power may be communicated in any approved IllitIlIl Ll.

Extending transversely of the frame extensions 1,

about midway between the ends of the machine, are

two yokes 1 1 the ends of which are bolted to the frame extensions referred to. Supported by said yokcs is a cylindrical hopper 8 with the upper part of which is connected an inclined feed-spout 9, only a portion of the latter being shown in this connection. The passage of material through the spout to the hopper is controlled by a gate 10 which is slidably mounted in a vertical position across the spout and said gate is manually operated through a rod 11 which is supported in suitable brackets secured to the hopper with one of which it has a threaded engagement, and is supplied with a hand-wheel 12 at its lower end. Arranged in the hopper is a spiral conveyor blade -13 \vhich is fixed on a vertical shaft 14 carrying at its upper end a bevel gear [5 which meshes with and is driven by a bevel gear loon one end of a horizontal shaft l7 which is journalcd in brackets secured to the hopper, and carries a drive pulley 17 at its outer end which may be driven in any suitable manner. Secured to the lower end of the hopper is a shoe 18 which Iits between and conforms to the curvature of the cylinders and serves to guide the material from the hopper between said cylinders.

.l'ournaled in the lower portion of the frame 1, are two shafts 20, 20, on which are fixed solid rollers 19, 19, faced with soft rubber coverings 2i, the surface of which is in close frictional contact with the periphery of the respective cylinders, so that the rotation of tlle latter drives said rollers.

Secured to the standards of the frame are horizontal bars 22 in which are journalcd shafts 23 on which are mounted scrapers 22 having extensions 24 through holes in which pass threaded rods 26 supplied with nuts. An expansion spring 25 surrounds each oi said rods between the extension 24 and the bar 22* thus exerting an upward pressure on the extension 24 whereby the scraper is held in close frictional contact with the periphery of the cylinder, and is thereby enabled to remove any surplus material adhering to the face of the cylinder adjoining the mold sections. Each of the cylinders 3 is formed with a hub portion 3 through which the shaft 2 passes, and with a countersunk peripheral face 3". On the face 3 is fitted a steel tire 27 in which are formed, by eounteisinking, a plurality of mold-sections 28. One side of each cylinder 3 is open and has fittedthereto a circular,

plate 29 which 'is fitted and bolted by bolts 30 to the hub and peripheral portions of the cylinder, and the joints are suitably packed to make the interior chamber 31 of the cylinder, steam-tight. Each of the shafts 2 is centrally-bored to form a longitudinal passsage 32 the inner end of which connects with radial passages through the shaft which register with corresponding passages 33 in the hub portion 3" of the cylinder, A pipe 34 passes through a stuffing-box 35-37 secured in the end of the shaft 2, and communicates with the passage 32-. The pipe 34 may be connected with any suitable means for supplying steam thereto The shaft 2 is boredfrom its opposite'end to provide a passage 38 the outer end of which communicates with a pipe 39 passing through a stuffing-box like that provided for the pipe 34. The inner end of the passage 38 is bored at right angles and communicates with a pipe 40 the outer end ofwhich communicates with the covered portion 41 of the con'densationgathering pan 42 which is arranged in the cylinder chamber 31 and suitably secured to'the inner peripheral wall of same. The pan is open for the greater portion of its length which extends transversely of the cylin dcr so that it will catch or gather the condensation of I [the steam that fills the chamber 31. Bearing-blocks 43 having slideways 43* are mounted on slideways 45 on.the frame 1, 1, (Fig. 7) and together with the plates 44 furnish journal hearings for the shafts 2. Angular uprights 47 formed with slideways 47 are bolted to the frame 1. Wedge-block 46 is slidably fitted to the slideways .4347, and is operated by a screw bolt 48 which enters a suitable 'recess in the block and has a threaded engagement with the frame extension 1, whereby the screwing up or down of the bolt will serve to vertically adjust the block 46 and consequently horizontally adjust the bearing block 43, the effect of such adjustment being to throw the cylinders v33 toward or away from each other.

49 represents one of thebriquets as formed in this machine.

A-maching constructed as above described will operate substantially as follows in the production of briquets:Steam will be introduced through the pipe 34 and channels 3233 to the interior 31 of each cylinder 3 until it and the'tire 27 are sufficiently heated to .effect the best results, the degree of heat required depending upon the nature and condition of the material being manufactured; The cylinders are then rotated toward each other and the material fed from the hopper 8 between them, the mold-sections being filled by compression and the resulting to said shafts, euch oi said cylinders having peripheral from snid cylinders, means (or rotatin briquets Will be more or less dried on their surface, so

that when they reach the under side of the cylinder they will drop by gravity on any suitable conveyor (not shown). Should any briquets lail to drop they will be carried around until they come in contact with the soft rubber roller covering 2i which will drive out the air produce a partial vacuum and pull out the briquet which will be discharged from the periphery ofthe roller by the expansion of the rubber as soonas it is relieved from pressure As the cylin ders revolve, the condensed steam falls into the pans 42 and is carried therefrom by gravity through the pipes 40, conduits 3S and pipes 3!).

It will be understood that the .ylindcrs rotate slowly thus giving suilicicnt time to subject the surface of the briquets to the heat of lb tire and adjacent part, and that the drying of the cxtorior ol' the briqucts not only facilitates the removal by. gravity, but serves to form a shell which materially aids in preventing the disintcgration oi thebriquet until it has pcrma nently set from subsequent thorough drying.

Havingthus described my invention what I claim as new and desire to secure by Lottcrslatent, is:

1. In :1 liriqucl machine, a supporting frame, shafts nil-- justably mounted on said frame. hollow cylinders ured to said shafts, said cylinders having one of their sides removable. a removable tire arranged on the periphery of each of said cylinders, said tire having, recesses in its outer face, means for introducing steam into said cylinders, means for rotating said cylinders and means for feed lug material into said recesses.

2. In :1 bliquet machine, a supporting frame, slni" justahly mounted on said frame, hollpw cylinders,

flanges, a recessed tire seated on said cylinders between said flanges, means for introducing; steam to the interior of said cylinders, means for carrying oll' condensed steam.

rid cylinders and means for feeding material to the rm 2:. In a hriquct machine, eyliinle .llllVlIlL', rcce their peripheral tacos, means for feeding,- material to suid recesses, HH'HHS for healing said cylinders, nnd means for expelling thc compressed material from s. d recesses, said means adapted to expel the air from the material and pro-. duce an outward suction on the material.

in testimony whereof I :illix' my signature in presence of two witnesses.
